One image, seven platforms, seven sizes
You’ve got a single photo and it needs to work everywhere, Instagram square post, Twitter header, Facebook cover, LinkedIn banner, YouTube thumbnail, TikTok vertical. Every platform has different dimensions, and uploading the wrong size means your image gets cropped awkwardly or shows with ugly letterboxing.
This tool takes one image and resizes it to the exact pixel dimensions each platform requires, or any custom size you type in. Pick a preset, watch the live preview update, choose cover or contain, and download the perfectly sized version. Everything runs in your browser using Canvas API, your image never leaves your device.
Available platform presets
Here’s what you’re working with:
- Instagram Post: 1080 x 1080 (square)
- Instagram Story: 1080 x 1920 (9:16 vertical)
- Twitter/X Header: 1500 x 500 (3:1 landscape)
- Facebook Cover: 820 x 312 (wide landscape)
- LinkedIn Banner: 1584 x 396 (ultra-wide)
- YouTube Thumbnail: 1280 x 720 (16:9)
- TikTok Video: 1080 x 1920 (9:16 vertical)
Each preset is based on the platform’s official recommended dimensions as of early 2026. They change occasionally, but these numbers are the current standard.
How it works
Upload your image. Pick a platform preset, or hit Custom and type your own width and height in pixels. The tool shows a live preview at those dimensions. Choose how the image fills the frame: Cover scales up and center-crops to fill edge to edge, Contain scales the whole image to fit and pads the gaps with a background colour you pick. Then choose your output format, PNG, JPEG, or WebP, with a quality slider for the two lossy ones.
Click Resize & Download and you’ve got a file at the exact pixel dimensions the platform expects. Drop it straight into your social media scheduler, upload it to the platform, or hand it to your designer. Done.
Why dedicated presets beat manual resizing
You could open Photoshop, look up the dimensions, create a new canvas, paste your image, and resize manually. For one image on one platform? Fine. But social media managers handle dozens of images across multiple platforms every week. Having instant presets saves a stupid amount of time.
The fit toggle is the key feature. When you’re turning a landscape photo into an Instagram square, what gets cut matters. Cover center-crops and works for most images. Contain keeps every pixel and letterboxes the rest, handy when you can’t afford to crop a logo or product shot, and you pick the fill colour so the padding matches your brand.
Freelance designers batch-process client deliverables with this. “Here are your assets for all platforms”, five minutes instead of thirty.
Platform dimension tips
Instagram squares at 1080x1080 are the bread and butter. Most photos need cropping from their original rectangle into a square, check that nothing critical sits at the edges.
Twitter headers at 1500x500 are weirdly wide. Text-heavy images need to sit in the center third because the profile picture overlaps the left side on desktop.
LinkedIn banners at 1584x396 are the widest format. Landscape photos and panoramas work best here. Avoid putting important text near the left edge, LinkedIn’s profile section overlaps it.
YouTube thumbnails at 1280x720 need big, bold visuals. Small details disappear at the sizes YouTube displays thumbnails. Focus on faces, large text, and high contrast.
FAQ
Does this compress the image too?
Depends on the format you pick. PNG is lossless, so what you download is pixel-perfect at the specified size. JPEG and WebP are lossy and come with a quality slider, drop it down for a smaller file, push it up for cleaner detail. The default sits at 92, which is a good balance for most uploads.
Can I upload any image format?
Any format your browser supports, JPEG, PNG, WebP, GIF (first frame), BMP, AVIF. The output is your choice of PNG, JPEG, or WebP, independent of the input format.
What if my image is smaller than the target dimensions?
The tool scales your image up to fill the target size. This can reduce sharpness if you’re scaling a small image dramatically. For best results, start with images that are at least as large as the target dimensions.
Can I adjust the crop position?
Cover mode crops from the center, which works well for the vast majority of images. If the subject is off-center, either switch to Contain so nothing gets cut, or use the Image Cropper tool first to frame your shot and then run it through the resizer.
Are the preset dimensions always up to date?
Social platforms occasionally change their recommended dimensions. These presets reflect the standards as of early 2026. We update them when platforms announce changes, but the core sizes (especially Instagram 1080x1080 and YouTube 1280x720) have been stable for years.
